Grade 8 / 80 Lifting Chain, Chain Size 7mm to 32mm

Grade 8 Short Link Lifting Chain

This Alloy Steel Chain is manufactured specifically for use in a chain sling assembly for lifting purposes. The chain is heat-treated for tensile strength and resistance to wear, whilst also allowing for shock absorption. The chain is easily identifiable with "MA8" embossed at metre intervals, indicating that the chain is also grade 8 or grade 80, as it is also referred to.

Chain Properties

• Work Load Limit (WLL) is the maximum load which the chains are designed to sustain in lifting use. The mean stress at this load is 200n/mm2 (MPA) and is based on a 4:1 factor of safety.
• Manufacturing Proof Force (MPF) is the force to which, during manufacture, the chain is subjected. The mean stress at this load is 500n/mm2 (MPA), which is 2.5 times the working load limit.
• Minimum Breaking Load (MBL) is the minimum force that the chain must withstand before failure. The mean stress at this load is 800n/mm2 (MPA). The minimum elongation before failure is 20%.
